Master-In Slave-
SPI Logic power supply.
SPI data is sent to the MCU by this pin. This data output changes on the
Out
negative edge of SCLK and when CS is high, this pin is high-impedance.

FETOUT
Output
External FET Gate
This pin controls an external SMART MOSFET by logic level. This output is also
called OUT6.
If OUT6 is not used in the application, this output pin is set to logic high when
the current sense output becomes valid when CSNS sync SPI bit is set to logic
[1].

This pin is the ground for the logic and analog circuitry of the device . (1)
Power supply pin.
This pin is the connection for an external tank capacitor (for internal use only).
Protected 35 m ? high side power output to the load.
Protected 10 m ?? high side power output to the load.
This pin is used to output a current proportional to OUT1:OUT5, FET in current,
Output
and it is used externally to generate a ground-referenced voltage for the
microcontroller to monitor output current. Moreover, this pin can report a voltage
proportional to the temperature on the GND flag.
OUT1:OUT5, FET in current sensing and Temperature feedback choice is SPI
programmable.
Notes
1. The pins 14, 17 and 23 must be shorted on the board.
